69121906 ÷ 166 
The aim is to understand the frequency of 166 in 69121906.

Step 1:
166 can be fit into 6 0 times, resulting in a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Include the next digit (9) from the dividend after 6, then repeat: 69 / 166

Let's proceed to step 2:
166 goes into 69 0 times with a remainder of 69.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 69 and we're left with 69.
Bring next digit (1) of the dividend behind the 69 and repeat the process: 691 / 166

Step 3:
When dividing 691 by 166, we get 4 with a remainder of 27.
Write down 4 as next digit of the result. 
Result so far: 4.0
Subtract 664 from 691 to get 27.
Append the next digit (2) from the dividend to 27 and continue with: 272 / 166

Let's proceed to step 4:
The number 166 fits into 272 1 times, leaving a remainder of 106.
Write down 1 as next digit of the result. 
Result so far: 41.0
The remainder is 106 after subtracting 166 from 272.
Grab the next digit (1) from the dividend, add it to 106, then carry on: 1061 / 166

On to step 5:
1061 divided by 166 is 6 with a remainder of 65.
Put 6 as the next digit of the answer. 
Result so far: 416.0
The remainder is 65 after subtracting 996 from 1061.
Fetch the next digit (9) from the dividend, attach it to 65 and continue: 659 / 166

Moving on to step 6:
659 divided by 166 is 3 with a remainder of 161.
The next digit of our result is 3. 
Result so far: 4163.0
Subtracting 498 from 659 leaves us with 161.
Include the next digit (0) from the dividend after 161, then repeat: 1610 / 166

Moving on to step 7:
When dividing 1610 by 166, we get 9 with a remainder of 116.
Record the quotient 9 as the next digit in the result. 
Result so far: 41639.0
If we subtract 1494 from 1610, we get 116.
Bring next digit (6) of the dividend behind the 116 and repeat the process: 1166 / 166

Advancing to step 8:
If we divide 1166 by 166, we get 7 and a remainder of 4.
The number 7 becomes the next digit in our result. 
Result so far: 416397.0
The remainder is 4 after subtracting 1162 from 1166.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 9:
The number 166 fits into 40 0 times, leaving a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 416397.0
Deduct 0 from 40 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 10:
166 can be fit into 400 2 times, resulting in a remainder of 68.
Write down 2 as next digit of the result. 
Result so far: 416397.02
Subtract 332 from 400 to get 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Advancing to step 11:
If we divide 680 by 166, we get 4 and a remainder of 16.
The number 4 becomes the next digit in our result. 
Result so far: 416397.024
The remainder is 16 after subtracting 664 from 680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 12:
166 goes into 160 0 times with a remainder of 160.
Use 0 as the next digit of our solution. 
Result so far: 416397.024
Deduct 0 from 160 and we're left with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Moving on to step 13:
The number 166 fits into 1600 9 times, leaving a remainder of 106.
The next digit of our result is 9. 
Result so far: 416397.02409
Deduct 1494 from 1600 and we're left with 106.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1060, and continue the process.

Step 14:
If we divide 1060 by 166, we get 6 and a remainder of 64.
Put 6 as the next digit of the answer. 
Result so far: 416397.024096
Deduct 996 from 1060 and we're left with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

On to step 15:
166 can be fit into 640 3 times, resulting in a remainder of 142.
Write down 3 as next digit of the result. 
Result so far: 416397.0240963
Subtracting 498 from 640 leaves us with 142.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1420, and continue the process.

Going ahead to step 16:
1420 divided by 166 is 8 with a remainder of 92.
The number 8 becomes the next digit in our result. 
Result so far: 416397.02409638
If we subtract 1328 from 1420, we get 92.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

Our division results in 416397.02409638 with a remaining 9.2e-08.
